Tappan Zee Hudson River Crossing [B6]

The existing Tappan Zee Bridge opened to traffic in 1955 and is a vital artery for commuters, travelers and commercial traffic. Today, bridge traffic has grown to about 138,000 vehicles per day; far more than the Tappan Zee was designed to support. The cost of maintaining the current bridge for the foreseeable future rivals the cost of a new bridge, with no appreciable improvements for the traveling public.

A consortium of some of the world's best-known and most highly-regarded design, engineering and construction firms was assembled to designed and build the replacement. This session will look at the state-of-the-art, twin-span replacement for the 3.1-mile Tappan Zee Bridge.
